Phalaenopsis orchid plant named ‘PHALGLODAL’

ABSTRACT

A new and distinct variety of  Phalaenopsis  plant named ‘PHALGLODAL’, particularly characterized by having small white flowers with a yellow lip, 1 to 3 peduncles that are medium long and sturdy, leaves that are oblong, and is propagated by meristem tissue culture, is disclosed.

Genus and species: Phalaenopsis hybrid.

Variety denomination: ‘PHALGLODAL’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct cultivar of Phalaenopsis plant, botanically known as Phalaenopsis hybrid of the Orchidaceae family, commonly referred to as moth orchid, and hereinafter referred to by the variety name ‘PHALGLODAL’.

The new Phalaenopsis plant is a product of a planned breeding program conducted by the inventor in Bleiswijk, The Netherlands. The objective of this breeding program was to create a new Phalaenopsis plant with numerous attractive and small white flowers with a yellow lip, suitable for potted plant production.

The new Phalaenopsis plant ‘PHALGLODAL’ is a result of cross-pollination made by the inventor in September 2008 in Bleiswijk, The Netherlands of the proprietary female, or seed parent, Phalaenopsis hybrid ‘00001-8917’ (unpatented) with the proprietary male, or pollen parent, Phalaenopsis hybrid ‘00001-8918’ (unpatented).

The new Phalaenopsis was selected by the inventor as a single plant within the progeny of the stated cross-pollination in a controlled greenhouse in Bleiswijk, The Netherlands in September 2011. Asexual reproduction of the new Phalaenopsis plant by meristem tissue culture since 2014 in Bleiswijk, The Netherlands, has demonstrated that the new variety reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations.

Plant Breeder's Rights for this variety have been applied for in Europe on Apr. 24, 2017. ‘PHALGLODAL’ has not been made publicly available or sold anywhere in the world more than one year prior to the effective filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Bleiswijk, The Netherlands and can be used to distinguish ‘PHALGLODAL’ as a new and distinct variety of Phalaenopsis plant.

-   -   1) Small white flowers with a yellow lip;     -   2) 1 to 3 peduncles;     -   3) Peduncle is medium long and sturdy; and     -   4) Shape of the leaf is oblong.

DESCRIPTION OF THE PHOTOGRAPHS

This new Phalaenopsis plant is illustrated by the accompanying photographs which show the overall plant habit including blooms, buds and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs were taken in a greenhouse in Bleiswijk, The Netherlands, from 42-week old plants in January 2018. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety.

FIG. 2 shows a close-up of a flower of ‘PHALGLODAL’.

FIG. 3 shows an overhead view of the leaves of ‘PHALGLODAL’.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘PHALGLODAL’. Plants of the new Phalaenopsis have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity and day length, without, however, any variance in genotype. The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2015 edition, except where general color terms of ordinary significance are used. The color values were determined under 4000-6000 lux natural light in a greenhouse in Bleiswijk, The Netherlands. Observations and measurements were made in January 2018 on flowering plants which were planted in 9 centimeter (diameter) pots. After in-vitro propagation, the plants were grown in nursery trays for 18-20 weeks, followed by transplantation to 9 centimeter (diameter) pots and grown in a greenhouse between 27° C. to 29° C. for 25 weeks, continued by a cooling period of 6 weeks between 18° C. to 20° C. and 11 weeks in a greenhouse of 21° C. Flowering occurs after 42-weeks in a 9 centimeter pot.

COMPARISON WITH PARENTAL LINES AND MOST SIMILAR VARIETIES

The female parent plant of ‘PHALGLODAL’, cultivar ‘00001-8917’ (unpatented), is no longer in existence, so a meaningful comparison cannot be made.

The male parent plant of ‘PHALGLODAL’, cultivar ‘00001-8918’ (unpatented), is no longer in existence, so a meaningful comparison cannot be made.

‘PHALGLODAL’ is most similar to the commercial Phalaenopsis plants named ‘PHALDUEL’ (U.S. Plant Pat. No. 28,256) and ‘PHALDUXI’ (U.S. Plant Pat. No. 25,680). ‘PHALGLODAL’ differs from the commercial variety ‘PHALDUEL’ in that ‘PHALGLODAL’ has a small callus, an elliptic to rounded apical lobe shape, green peduncles, and lateral sepals with light yellow-green over color and very small purple-red dots at the base, whereas ‘PHALDUEL’ has a medium callus, a triangular apical lobe shape, a mix of green and brown colored peduncles, and lateral sepals with light yellow-green over color. Additionally, ‘PHALGLODAL’ has shorter dorsal sepals and shorter whiskers than ‘PHALDUEL’.

‘PHALGLODAL’ differs from the commercial variety ‘PHALDUXI’ in that ‘PHALGLODAL’ has a small callus and an elliptic to rounded apical lobe shape, whereas ‘PHALDUXI’ has a medium callus and a triangular apical lobe shape. Additionally, ‘PHALGLODAL’ has shorter dorsal sepals and shorter whiskers than ‘PHALDUXI’. 

I claim:
 1. A new and distinct variety of Phalaenopsis plant named ‘PHALGLODAL’, substantially as described and illustrated herein.
